TECHNICAL FIELD OF THE INVENTION

The present invention relates to the technical field of baby cribs, and more particularly, to an intelligent baby crib.

BACKGROUND OF THE INVENTION

A baby crib is a small bed especially designed for infants and very young children. The marketplace is filled with a great variety of baby cribs with styles and features. Although their prices and functions are very different, safety and practicability are always regarded as key factors for selecting a baby crib. Traditional baby cribs sold on the market provide various choices and experiences to the users. When lulling a baby to sleep, a caregiver usually shakes the baby crib or sings a lullaby. However, the baby needs to be constantly nursed even when he/she falls asleep. For instance, a baby soiled diaper will probably baby wake up and cry at any time even during the night. At this time, the parents must immediately replace the baby's diaper and lull the baby back to sleep again, making the parents exhausted.

Presently, some baby cribs sold on the market possess functions such as automatic swinging, music playing, monitoring and alarming, alleviating the caregiver's burden to a certain degree. However, their structures are not reasonable, leading to several problems. For instance, a baby may frequently roll over in the baby crib. When the baby turns to sleep on her side, instead of lying on her back, the height of her head can be changed accordingly. However, the bed plate of the traditional baby crib cannot be regulated according to her physical movements, resulting in problems relating to milk-vomiting or difficult breathing, creating more stress for the parents. Moreover, some baby cribs capable of automatically swinging usually adopt an arc-shaped slide structure as the main frame, thereby supporting and enabling the bed plate to roll on the slide back and forth. Such a design is not humanized, and has shortcomings, such as complicated structure and difficult control of swing range and frequency, resulting in limited functions and low level of intelligence.

In conclusion, the shortcomings of traditional baby cribs are urgent problems that need to be solved for those skilled in this field.

The main purposes of the present invention are: first, the height of the bedstead 1 can be regulated on the base 6, enabling the caregiver to conveniently nurse the baby at a proper height; second, the bed plate 2 can be stretched and deformed back and forth to regulate the height difference between the baby's head and body during sleep, thereby solving the problems relating to milk-vomiting and difficult breathing due to the baby's sleeping postures; third, the bed plate 2 can swing left and right on the bedstead 1, thereby creating a comfortable sleeping environment for the baby. Thus, the time and labor consumed by manually shaking the baby crib can be saved. An armrest portion 12 is disposed at the rear end of the bedstead 1, and a control panel 13 and a music player are disposed on the armrest portion 12. The control panel 13, which is disposed on the upper end surface of the armrest portion 12, is electrically connected to the music player, the swing mechanism, the stretching mechanism and the elevating mechanism through connecting wires. The baby crib of the present invention is equipped with moving components capable of greatly improving the portability of the baby crib, thus enabling the baby to be conveniently nursed during outdoor activities. The integrated control panel is placed on the armrest portion 12, which can significantly enhance the operating convenience.

All of the vertical sections of the bed plate 2 are recessed and arc-shaped, making the bed plate to be an arc-shaped integral structure. The arc-shaped bed plate 2 can ensure that the baby's head is always kept higher than his/her body. Thus, a newborn infant can be kept lying on his/her back, effectively reducing the frequency of turning or rolling over. Consequently, problems relating to milk-vomiting and difficult breathing during sleep can be effectively solved.

Furthermore, the bed plate 2 comprises a front base plate 21, a rear base plate 22 and a plurality of transitional base plates 23. The plurality of transitional base plates 23 is sequentially hinged to form an integral linking structure.
